IEQ Investigation Process

Identify deficiencies that may impact IEQ and/or sources of odor concerns. Typically includes the following depending on the nature of concern, but not limited to:

  • interview/questionnaire of concern individual(s)
  • inspection above drop ceiling (condition of roof deck, pipe insulation, return air plenum)
  • inspection of ventilation system (operation of variable air volume box and outdoor air dampers, check controls, measurements of carbon dioxide, temperature and relative humidity, sources near outdoor air intake, measure return and supply air volume, cleanliness of coils, liner and condensate pan)
  • inspection of exterior
  • inspection below drop ceiling (housekeeping, sink and floor drain traps, signs of past and present moisture concern via visual and/or moisture meter, mold growth, ensure connection of current and capping of abandoned sanitary vents, odorizers, excessive plants and fabric items, identify potential pathways, and measure volatile organic compounds, carbon monoxide, and lighting)

Date of Assessment: July 8, 2021

The portable was finished with drywall, floor tile, and a drop ceiling.

Surfaces were assessed for relative humidity mold growth. No mold growth was identified.

The drywall was probed with a moisture meter in areas prone to moisture intrusion such as near doors and under windows. No elevated moisture was detected in the drywall.

The area was screened with a thermal infrared camera. No anomalies indicative of moisture intrusion were noted. 

Areas above the drop ceiling were assessed. No moldy/musty odors or moisture intrusion concerns were noted.

The temperature (76.3 degrees Fahrenheit) and the relative humidity (59.9%) were acceptable.

An odor very typical of HCPSS portables was noted within the space. Depending on the temperature and humidity, portables can have varying intensities of odor that are associated with their construction materials (mainly wood and fiberglass insulation).

No further action appears warranted.
